IPC: G02B26/10
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To reduce a lowering of the amount of laser light at low resolution by a method wherein the scanning timing only for a horizontal scanning range and the scanning timing only for a non-image range are produced in a predetermined order by a timing forming means so as to control a laser driving means by the resistant timing. SOLUTION: An engine controller 108 controls the driving of a laser diode 101 on the basis of the information sent from a BD detection circuit 106 and from a number of frequency changing-over signal sent from a resolution changing-over part. Concretely, the engine controller 108 drives a scanner motor 1141 and receives horizontal synchronizing signal from the BD detection circuit 106 so as to emit light from the laser diode 101 by means of a laser driver 144. Next, the engine controller 108 increases the amount of light emitted from the laser diode 101 to the normal amount of light through the adjusting controlling of the amount of laser light outside an image range. As a result, when the resolution changing-over signal is set to realize the resolution of 300dpi, outputting is performed at the timing same as that at the resolution of 600dpi.

IPC: G11B5/09
Filed: 1988-04-26
Abstract: PURPOSE:To make an electric current larger than the rated current of an IC to flow through a head winding so as to realize high-speed writing by providing electric switches between the IC and head windings and electrically cutting off one end of the winding which is not driven from the IC. CONSTITUTION:In a magnetic recorder which performs magnetic recording by making electric currents to alternately flow by alternately driving the head windings on both sides of a head H provided with an intermediate tap by using an IC having a signal recording function, transistors QA1 and QB1 are used as electric switches between ends (a) and (b) of the head windings of both sides of the head H and the input terminals T1 and T2 of the IC and the potential to ground va and vb at both ends of the head windings is detected. When the potential at both ends of the windings becomes higher than a certain level, the transistors QA1 and QB1 are respectively turned off so as to prevent the terminal potential v1 and v2 from getting higher. Since the voltages to ground of the terminals and the voltage across the terminals of the IC can be brought nearer to VCC and the 1/2 of the voltage across the head, high-speed writing can be realized.

Title: Apparatus for producing single crystal
IPC: C30B29/42
Filed: 1992-03-27
Abstract: PURPOSE:To produce the subject high-quality single crystal free from crystal defect while preventing sticking or thermal stress by the horizontal boat method. CONSTITUTION:A heat-insulating member 23 is sandwiched between the lower surface of a qualtz boat 20 accommodating a raw material for growing a single crystal and a qualtz reaction tube 11 and the raw material for growing a single crystal is heated by a heating furnace 10 so as to be converted to a fused liquid 21. Thereby, the heat-insulating member 23 prevents heat of the heating furnace 10 from transferring directly to the fused liquid 21 and the temperature fluctuation of the fused liquid 21 in contact with the inner surface of the qualtz boat 20 can be prevented. The temperature of the fused liquid 21 can be, therefore, remarkably lowered and the temperature distribution is reduced in the fused liquid 21 is reduced in the vertical direction and in the axial direction of growth. Occurrence of dislocation due to sticking or thermal stress is consequently reduced, thus producing the objective high-quality single crystal.

An exothermic device is provided therein with a reaction detection means 2 for sensing changes in the temp. of a reaction path and hence the occurrence of the exothermic reaction. Also provided is reaction initiating means 3 which starts the exothermic reaction by disrupting the normal state of the reaction path and imparting a chance for the exothermic reaction to take place, when the information from the reaction detection means senses the exothermic reaction as being in the state of stoppage. The device provided with these two means permit a more effective exothermic reaction. With respect to the waveform of the current to be applied, an pulse wave is more preferable than pulsating one.
